TITLE: A Possible Mechanism for-the 0~7 Intensification of Weak
Shock Waves in the Turbulent CorPL-ustion Zone (The Theory
of High-frequency Vibrations cf Flames)

ABSTRACT: The paper is a continuation of previous work (Ref 1)~
An analytical relationship is obtained between the
dimensionless change in pressure in a weak shock wave and
the dimensionless increase lin combustion velocity
arising in an idealised combustion chamberlof a reactive
engine. Special attention is given to the dependence of
C3
the intensity of the shock wave on combustion propa.gation
It is
velocity and vice versa. shown quantitatively
that the movement of a shock wave through the combustion
zone causes an increase in the -~relocity of turbulent
combustion. A criterion is laid down for the intensifi-
cation of weak shoc_~z -%,raves in t't,e combustion zone,
Card equivalent to a condition for the establishment of high
frequency vibrations in the ideal-ised combustion chamber

TEXT: Without considering physico-chemical processes in the combustion
chamber of a rocket enCine, the authors identify the burning zone in the rocket.
engine chamber with the zone of strong discontinuity in which a substance goes
over from the initial state into the final state at the expense of energy libera-
tion. The state of perfect gas formed at fuel evaporation is assumed for the
initial state. In this schematization, operational conditions of rocket engines
are represented by Gugonio adiabatic curve (its lower branch). Based on a cer-
tain analogy of burning in a rocket engine and in a detonation wave, the aathors
apply to burning in the rocket engine the criterion of instability of the plane
front of burning at detonation

TITLE: Detonation Processes
PERIODICAL: Vestnik Akademii nauk SSSR, 1960, Nr 2, pp 12-20 (USSR)
ABSTRACTt In this article the author reports on the study of detonation pro-
cesses and describes the development of the detonation theory.1
First, he explains the fundamental principles of this theory (Figs
1 and 2), which was later completed by Ya. B. Zelldovich (Fig
This theory which has been developed for gases is successfully
applied to the detonation of condensed explosives. Its reliability
in calculating detonations of explosives was improved by the de-
velopment of a theoretically founded equation of state for the
explosion products. Numerous empirical formulas were replaced by
this equation which was derived by L. D. Landau and K. P.
Stanyukovich. In spite of the apparent perfection of the detonatior
theory it was not possible to explain an experimentally proyed
fact identified by the British scientists Campbell and Woodhead
in 1926 as a spin detonation with the help of the scheme of a plaau
detonation (Fig 4). For comparison, the author shows a normal det-
Card 1/3 onation in figure 5. The spin was later detected also in other

slowly reacting mixtures by Kh. A. Rakipova, Ya. K. Troshin, and
the author of the article under review. The author showed (Ref 2)
that the spin nucleus represents an oblique (discontinuous) shook
wave in which the mixture detonates much more easily than in a
plane wave, as a result of higher temperature and pressure. An
oblique detonation is schematically represented in figure 6. The
spin detonation as a detonation directed by the oblique compression
shock could be sufficiently founded. Yu. 1. Denisov and Ya. K.
Troshin assume that the angle K in figure 6 may assume the shape
shown in figure 7. The attempt was made to apply the classical
theory of plane detonation to spin detonation. The rate of spin
detonation, the state and the velocity of the combustion products
could be determined approximately. Determination of the reaction
zone of a spin detonation as a three-dimensional process can be
facilitated by transforming this problem into a two-dimensional
one. Figure 8 illustrates a "normal" detonation which gives a
reticular impression and in which a similar event as in the ause
of spin detonation was detected. In connection with these experi-
ments the author performed an approximate quantitative analysis
of the unsteadiness of a plane detonation wave (Ref 4). It was
Card 2/3 found that the intensity of the detonation is increased by this

unsteadiness due to the formation of zones with higher temperatures
than those of the plane wave. These zones are reliable detonation
centers. The unsteadiness of one type of detonation causes new
steadier types. The practical application of the detonation theory
is illustrated by the author by the combustion\\processes taking
place in rocket chambers (Fig 9). There are 9 figures and 5 Soviet
references.

ABSTRACT: The life of Academician Igor' Yevgeniyevich Tamm is described
on the occasion of bis 70th birthday. 14511owing are the essential fea-
tures of this biography. He was born Tuly 8, 1895, in Vladivostok. His
general education was obtained in the Elizavetgrad (now Kirovograd)
gymnasium. In 1913, he was admitted to the Edinburgh University (Scot-
land) but, in 1914, returned to Russia and entered the University of
Moscow. In 1915, he voluntarily entered the military service and serv-
ed as a hospital attendant. In 1917, he was elected to the Elizavetgrad
Soviet and was sent., as a delegate, to the first Convention of Soviets
in Petrograd. After graduation, he taught physics (1921-1922) in the
Odessa Polytechnic Institute and in 1922 returned to the Moscow Univer-
sity. In 1934, he became head of the theoretical department of the
Institute of Physics of AN SSSR im. P. N. Lebedev (EILNIand has held

this office up to the present time. In 1945, he presented a method
(based on the quantum mechanics) for solution of problems of meson
physics. This method is similar to that proposed in 1950 by Dancoff in
U.3.A. Thus, it was called the Tamm-Dancoff method. He predicted
(together with S. A. Alltshuller) the existence of magnetic moment in
neutron. In 1950, he proposed (together with A. D. Sakharov) a method---.:~'
for plasma confinement by magnetic field. In 1958~, he received (wit.*a
P. A. Cerenkov and I. M. Frank) the Nobel Prize for his theoretical
study of the coherent radiation caused in a medium. by a fast moving
electron (Cerenkov radiation). He also was bestowed many high Soviet
awards. Detailed information on his works and scientific achievements
were,given in the publications of V. L. Ginzburg, Ye. L. Feynberg and
A. D. gakhax27-,- These publications were ci d in the present RMcle.

TEXT: Symmetrical and asymmetrical merocyaninocarbocyanine derivatives
are synthesized from 1-cyclohexyl-3-methylimidazolinone-4 with the
residues of various heterocyclic bases in merocyanic and carbocyanic
components of the molecule. An investigation is made of the structural
dependence of the colors of these compounds and of the nature of the
clectron density distribution in the chromophores of the molecule.
